Application December 19, 1949, Serial No. 133,769

This invention relates to a tool especially designed for use in removing and in applying rivets on the door checks of certain makes of automobiles, but also having other uses.

In certain makes of automobiles the door checks are fastened to the body by means of rivets. To remove these, the usual practice is to knock them out as the space is very limited in which to work and the rivets are hard to get to. Ordinary rivet removing tools cannot be used and frequently damage is done which requires re-welding. With my tool, it is a simple and instantaneous job to punch out these rivets and thereby save considerable time. With the same tool, I am also able to easily and very quickly replace and secure the rivets.

It is, therefore, an object of this invention to provide a rivet tool which will make it easy to remove or replace rivets, the tool being formed of a pair of pivoted jaws with relatively long handles so that suflicient pressure may be exerted to perform the required operation.

Another object of this invention is to provide a rivet tool which can be quickly converted from a rivet removing tool to a rivet applying tool. One of the jaws is provided with a slot through which the rivet being removed is adapted to pass, and when a rivet is to be applied or replaced, the slot is covered by a sliding anvil or abutment which is carried by the slotted jaw, and at this time the removing pin is reversed to present a rivet upsetting head to the anvil.

With the above and other objects in view, my invention consists in the arrangement, combination and details of construction disclosed in the drawings and specification, and then more particularly pointed out in the appended claims.

In the drawings:

Figure 1 is a detailed plan view partly broken away'and in section of a rivet removing and applying tool constructed according to an embodiment of this invention.

Figure 2 is a fragmentary longitudinal section of the tool in rivet upsetting position.

Figure 3 is a fragmentary side elevation of the tool in rivet removing position.

Figure 4 is a fragmentary sectional view taken on the line 4-4 of Figure 3.

Figure 5 is a detailed front elevation of the tool in the position shown in Figure 3.

Figure 6 is a sectional view taken on the line 6-6 of Figure 3.

Referring to the drawings, the numerals l and II designate generally a pair of jaw members which are pivotally connected together, the

jaw member l0 being provided with a pair of cars l2 between which the rear end of jaw ll Claims. (Cl. 78-46) engages, and a pivot member l3 engages through the ears l2 and the rear portion of jaw member ll. Jaw member I 0 has extending rearwardly therefrom an elongated handle I4 which is fixed relative to the jaw. 10, and jaw'member II has pivotally mounted thereon a handle or lever IS.

The forward end of the handle or lever l5.

rockably engages between a pair of cars 16 carried by the jaw member ll forwardly of the pivot l3 and a pivot l1 engages through the ears l6 and the forward end of handle or lever l5.

A laterally offset lever I8 is fixedly carried by the handle I5 projecting forwardly of the pivot l1, and a pair of links l9 are pivotally secured as by a pivot 20 to the lever l8 and are pivotally secured as by a pivot 2| to the jaw member ID at a point closely adjacent the forward end of jaw member l0.

Jaw member if! is formed with'an inwardly opening socket 22 adjacent the forward end thereof and a relatively small diameter opening 23 extends from the bottom of the socket 22 as shown in Figure 2. A rivet engaging pin 24 is removably mounted in the socket 22 and includes.

a relatively large. diameter body 25 formed with a rivet upsetting head 26 which is adapted to project from the inner face of jaw member I0.

A relatively small diameter shank 21 extends from the body 25 oppositely from the head 26 and terminates in a relatively small diameter stud 28. The shank 21 is adapted to engage through the opening 23 as shown in Figure 2 when the tool is used for applying a rivet.

The jaw H has slidably mounted thereon an anvil 29 constructed in the form of an elongated plate which is formed with a longitudinally extended elongated opening or slot 30 through which a securing member 3| engages for slidably mounting the anvil or plate 29 on the inner face of jaw member I l. The plate or anvil 29 has extending from the opposite lengthwise edges thereof pairs of lugs 32 which engage on the. opposite sides of jaw member H for holding the anvil or plate 29 against lateral movement.

Jaw member I I is provided at the forward end thereof with a forwardly opening slot 33 within which the shank 21 of the rivet engaging tool 24 is adapted to loosely engage when the rivet engaging member 24 is reversed as shown in Figure 3. With rivet engaging member 24 reversed or in rivet removing position the head 26 will be disposed innermost with respect to the socket 22, and the small stud 28 will engage with the rivet so that when pressure is applied to the handles I4 and I5 so asto rock jaw member I! toward jaw member ID, the rivet willbe pushed out of the work and into the slot 23. At this time the anvil 29 will be in a retracted position as shown in full lines in Figures 3 and 4.

In the use and operation of this device when it is desired to remove a rivet the rivet engagin member 24 is mounted in the socket 22 of jaw ID with the body 25 innermost and the shank 21 projecting in the direction of jaw member H.

The stud 28 is engaged with the end of the rivet, preferably the upset end of the rivet, and pressure is then applied to the handle levers l4 and I5. These handles or levers are of sufiicient length so that sufficient pressure or leverage will be obtained to forcibly remove the rivet. When the new rivet is to be replaced the anvil 29 is moved forwardly to a position overlying the slot 22, and the rivet engaging member 2a is reversed to the position shown in Figure 2.

The upsetting head 26 will engage the rivet end, and upon pressure being applied to the handles or levers M and IS, the rivet will be upset and tightly secured in the work.

As'shown in Figure l handle or lever l5 constitutes a magazine bein formed at its rear end with an elongated bore 36 within which rivet engaging members are adapted to engage, and the bore 34 is normally closed by means of a threaded plug 35.

The anvil 29 is frictionally held in adjusted position either overlying the slot 33 or in a rear inoperative position by means of a spring 34 which is interposed between screw 31 and the anvil 29. In this manner the anvil cannot accidentally move out of its adjusted position.
